just wondering if anyones used a t34 on an r and what its like compared to the t28?
(it will be a t34 comp with gtir back end, think its .86 housing?)

currently running 340bhp on the t28 and its maxed out.


is it likely to give more of a kick on boost?

(i know the compressor housing doesnt have the 3 bolt flange for the intercooler pipe but thats not a problem)

cheers

thats a 3071 but minus actuator and has a 4" inlet that a few people are finding even when told that they dont fit lol

If you buy a GT3071R you need one with a 2.75" inlet matey, Otherwise you will need a to mod your manifold and down pipe to get it to fit.

so is a t28, your point exactly???

a t34 is ganna be alot better than a t28. and it wont cost much to rebuild if it ever needs it, unlike a roller cored turbo.

the t34 will be a straight swap too, and its alot cheaper.

my stage 1 t28 is running 340bhp, which is holding me back. so im trying to find out wether the t34 will be more suitable. im told the t28 is rated to 300bhp and the t34 is rated to 350bhp.

The point is that that turbo is old hat, But if you want to fit it why ask people's opinions if you don't like what you hear :roll: :der: .

Personally I'd stick to bolting that old 5hit up to the nearest old rusty ford and be done with it ;-) .

If you want a quick spooling 350-450 bhp turbo go for ether the 2871 (400bhp) or the 3071 (450bhp), I can't see why it being easy to rebuild has anything to do with it myself, The standard turbo has lasted 10-14 years on most peoples car's, So I can't see you needing a turbo rebuild any time this side of 2015 :doh: :lol: :lol: :lol: :lol: .

no, i do want to hear peoples opinions on the t34, however the only opinions ive been given so far are from people who probably havent even tried a t34 on a pulsar.... thats the whole point of this post, to find out wether it'l be any good or not??

so if you think its no good, an explanation of why its no good would be more help, not just because its 'old news' and not a 'roller bearing turbo'... geez

ps about the turbo rebuild bit, im just thinking ahead incase the worst ever happens ie blowing a piston and having it go through a £1k roller bearing turbo...

What's the chance of someone having bolted one of those up to a pulsar ?, Pretty slim I reckon.

Why not ask the ford lot what they think of it, Just an idea lol lol.

that one isnt, but my mate who works at turbo developments has one that will go straight onto the stock manifold, and downpipe. he built it for some guy who uses them on his vw 20v turbo conversions. the only thing different would be the lack of flange ontop of the comp and a slightly bigger inlet.

plus the comp housing he would use doesnt have that mount for the actuator like the one above,and it would sit the right way round, unlike the one above.

this is what i mean, for £500 and it will go straight on. i think the weakness of the t28 is th einlet, the exhaust housing is huge on the gtir as standard, whack a t34 inlet on it and i would have thought i would be alot better.

i think the reason you dont see many about on pulsars is that they are quite long winded to build (this is what matey told me who owns turbo developments) theres alot of machining involved apperently.

Still waiting on some shims!
T34 is old technology. Even the Ford lot use Hybrid/Modified versions!

You'll manage around 380bhp @ 1.4 - 1.5bar but the spool and delivery will be rubbish!

You can use a small GT28RS turbo to get the same power but with much less lag!

You could even use a larger 450bhp capable GT Series turbo which you could have spool quicker with better delivery than the old T34.

im told it wont be no more laggy than the t28 is. would it have more kick when it hits boost than a 28?

The T34 is more laggy than the T28!! Also worth a look into why Ford changed the the production turbo from T34 to T28 in the later Escort Cosworths.

Also remember you are just comparing one old technology turbo with another. You should be comparing your T34 to a modern day alternative. No one uses that old T-series technology anymore. Infact we are even further along with the Garrett VNT Turbos as in the new 911 Turbo as they are now cheaper to manufacture from when first concieved..

hmm think the 3071 is worth saving for then. i hear they suffer from boost creep unless they are ported? any truth in that?

I have a T3/4 rollerbearing turbo on mine, but mine has a top mount exhaust manifold, so i cant really help you regarding standard manifold fitment. The car is running 348bhp at the wheels, and 400ft/lbs torque, the car drives fantastically, and the car does not suffer from lots of lag, spools up rather fast. I cant comment on what it is like compared to other turbo setups because i have never tried them, but i would reccommend you listen to what otheres have said, but i have no problems using my t3/4.
